摘要
为了提高输煤系统的自动化运行水平,有必要进一步研究输煤程控设计方案。文章介绍了输煤程控系统的现状,分析了自动配煤功能难以实现的原因,阐述了改进的自动配煤设计方案,以某2×330MW燃煤火力发电厂输煤程控系统的运行结果表明,该设计方案的合理性和有效性。文中还提出进一步改进的建议。
In order to improve the automation level of coal handling system, it is necessary to study further the design scheme of coal conveying control system. The paper introduces the present situations of coal conveying programmed control system, analyzes the difficulties realizing automatic coal blending function, and describes the improved design schme of automatic coal blending.The operation result of coal conveying programmed control system of a 2 × 300 MW coal-fired power plant has verified the rationality and validity of the desing scheme.
